We present a formal compatibility and falsifiability assessment of the SEXA Unified Field Model in the low-depth (OFF-state) regime. The analysis evaluates whether the framework reduces consistently to established limits of General Relativity (GR) and Quantum Field Theory (QFT) under weak-field and perturbative conditions. Explicit benchmarks examined include gravitational light bending, Mercury perihelion precession, solar gravitational redshift, Shapiro time delay, frame-dragging (Lense–Thirring effect), relativistic clock drift, binary inspiral decay via gravitational radiation reaction, relativistic dispersion relations, Casimir vacuum scaling, and leading-order electron g−2. In each case, the SEXA framework preserves the required curvature invariants, orbital corrections, relativistic energy-momentum structure, and first-order loop behavior in the reduction limit, demonstrating compatibility with empirically verified GR and QFT predictions. Beyond compatibility, the model defines an activation sector governed by an explicit coupling parameter χ = σ/Σc, with a specified hard-switch threshold at 10⁸ Pa. This ON-state sector predicts a measurable Yukawa-type deviation accessible via torsion-balance experimentation. A falsifiable ON/OFF protocol is therefore formally defined, distinguishing the empirically verified low-depth regime from the experimentally pending activation regime.
